NGN Architectures, Protocols and Services

Angebote / Angebote:

This book provides comprehensive coverage of NGN (Next Generation Network) architectures, protocols and services. It covers the foundations of NGN such as Internet technologies (as defined by IETF), fixed broadband (as defined by ITU, IEEE) and mobile broadband (as defined by 3GPP, IEEE, ITU), including LTE/LTE-Advanced and Mobile WiMAX 2.0. The book focuses on the NGN as defined by the ITU, including Quality of Service (QoS), service architectures, IMS (IP Multimedia Subsystem), control and signalling protocols, security, identity management, service overlay networks, as well as NGN business models. It also covers NGN services, including QoS-enabled VoIP, IPTV, web services in NGN, peer-to-peer services, ubiquitous sensor networks, VPN services in NGN, Internet of Things and Web of Things, as well as business and regulation aspects. Further, the book includes a transition from PSTN and best-effort Internet towards the NGN, and provides advanced topics such as IPv6-based NGN, network virtualization and future packet-based networks. The book is aimed at managers, engineers and employees from regulators, government organizations, telecommunication/ICT companies, to students and professors, and to everyone who is interested in the implementation and regulation of NGN architectures, protocols and services, including technology, regulation and business aspects. Key features: * Provides full up-to-date coverage of the standardized NGN architectures, protocols and services * Gives the "big picture" for NGN by explaining the correlation and synergy between NGN and the other existing standardized technologies (from ITU, IETF, 3GPP and IEEE), in a single book
